Imprint of DES super-structures on the Cosmic Microwave Background
A. Kovács, C. Sánchez, J. García-Bellido +58
Small temperature anisotropies in the Cosmic Microwave Background can be sourced by density perturbations via the late-time integrated Sachs-Wolfe effect. Large voids and superclus…
Weak lensing magnification in the Dark Energy Survey Science Verification Data
M. Garcia-Fernandez, E. Sánchez, I. Sevilla-Noarbe +68
In this paper the effect of weak lensing magnification on galaxy number counts is studied by cross-correlating the positions of two galaxy samples, separated by redshift, using dat…
Weak-lensing mass calibration of redMaPPer galaxy clusters in Dark Energy Survey Science Verification data
P. Melchior, D. Gruen, T. McClintock +78
We use weak-lensing shear measurements to determine the mean mass of optically selected galaxy clusters in Dark Energy Survey Science Verification data. In a blinded analysis, we s…
Simultaneous Constraints on Cosmology and Photometric Redshift Bias from Weak Lensing and Galaxy Clustering
S Samuroff, MA Troxel, SL Bridle +5
We investigate the expected cosmological constraints from a combination of weak lensing and large-scale galaxy clustering using realistic redshift distributions. Introducing a syst…
Testing the lognormality of the galaxy and weak lensing convergence distributions from Dark Energy Survey maps
L. Clerkin, D. Kirk, M. Manera +57
It is well known that the probability distribution function (PDF) of galaxy density contrast is approximately lognormal; whether the PDF of mass fluctuations derived from weak lens…
Cosmology from large scale galaxy clustering and galaxy-galaxy lensing with Dark Energy Survey Science Verification data
Juliana Kwan, Carles Sanchez, Joseph Clampitt +80
We present cosmological constraints from the Dark Energy Survey (DES) using a combined analysis of angular clustering of red galaxies and their cross-correlation with weak gravitat…
